Heavy Rail

Parsons’ early association with Chicago’s transit system and original subways in the 1930s led to our pioneering work on the Toronto, Canada subway system in the 1940s and more recently to the world-class Washington, DC Metro system. Major transit system assignments stretch from Singapore to New York, and include the South Broad Street Subway extension in Philadelphia, an extension of San Francisco’s BART system, and systems in Chicago, Atlanta, Baltimore, Taiwan, and Bangkok. Where underground solutions are called for, our urban tunneling expertise is well demonstrated, from the $5.3 billion Los Angeles Metro Rail to the Singapore Mass Rapid Transit System and the $10 billion Washington, DC Metro Area Transit System.
